[0016] Preferably, a conical plate is fixedly mounted on the rear side of the lower end of the liquid-jetting plate, and an eccentric plate is fixedly mounted on the gear shaft corresponding to the conical plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the MNS switch cabinet door panel to be cut is fixed on a fixed table, and the laser cutting equipment and the linear motor are started. The linear motor drives the laser cutting equipment to move from back to front. The laser cutting equipment is convenient for laser cutting and forming the MNS switch cabinet door panel on the fixed table. At the same time, when the laser cutting equipment moves from back to front, it will also drive the U-shaped frame to move synchronously. The cooling water is sprayed from the main nozzle through the external water tank and the water pump connected by the external water pipe. The main nozzles on both sides are convenient for spraying cooling water on the upper and lower sides of the slit of the MNS switch cabinet door panel, so that the slit can be well and evenly cooled, and the cooling effect is good.

[0018] 2. In the present invention, when the U-shaped frame moves, it will also drive the top seam plate to move synchronously. The puncture strip is arranged to facilitate the top seam plate to be smoothly inserted into the slit of the MNS switch cabinet door panel and slide in the slit. The top seam plate is made of a deformable material, so when the top seam plate slides in the slit, it will be squeezed by the slit and then deformed, so that the two ends of the top seam plate can be closely abutted and slide in the slit. At this time, the oblique groove will form a space with the two ends of the inner wall of the slit. When the cooling water is transported inside the external water pipe, the cooling water will also be synchronously sprayed out from the auxiliary nozzle, and the sprayed cooling water It will spray vertically to the inner front side of the inclined groove. Under the effect of the V-shaped arc of the inclined groove, the cooling water is discharged outward from the inner rear end of the inclined groove (the inner rear end of the inclined groove is shorter than the inner front end), which is conducive to cooling the middle part of the inner wall of the slit by the cooling water. Combined with the main nozzle cooling the upper and lower ends of the slit of the MNS switch cabinet door panel, the inner middle part and the upper and lower ends of the slit can be cooled synchronously at the same time, thereby ensuring uniform cooling of different positions of the slit, with better cooling effect, avoiding the situation that the middle part of the slit cannot be cooled evenly and timely due to the thick door panel of the MNS switch cabinet.

[0019] 3. In the present invention, when the U-shaped frame moves forward, it will also drive the gear shaft to move forward synchronously. The gear shaft and the rack are constantly meshing, which will drive the gear shaft to rotate on the U-shaped frame. The gear shaft will also drive the blades to rotate synchronously. The wind generated by the blades will blow from the wind guide cover to the slit on the upper side, which is beneficial to assist in cooling the slit.

[0020] 4. In the present invention, when the U-shaped frame moves forward, it will also drive the support plate, the air guide cover and the magnetic plate to move synchronously. When the magnetic plate passes through the magnetic block plate in sequence, it will be affected by the magnetic attraction of the magnetic block plate, and the magnetic plate will then approach the magnetic block plate. The magnetic plate drives the air guide cover to rotate on the support plate and compress the spring. When the magnetic plate moves to the gap between the magnetic blocks on the magnetic block plate, it will reset under the action of the spring. In this way, the reciprocating swing of the air guide cover is repeatedly realized, which is conducive to evenly blowing the cooling air generated when the blades rotate to the lower side and inside the slit of the MNS switch cabinet door panel, which is conducive to improving the cooling effect at the slit.

[0021] 5. In the present invention, when the gear shaft rotates, the eccentric plate will be driven to rotate synchronously, the eccentric plate will continuously squeeze the conical plate, the conical plate will drive the liquid throwing plate and the rotating shaft to rotate on the fixed plate, compress the torsion spring, and the liquid throwing plate is conducive to throwing the cooling water collected in the collection box to the slit of the MNS switch cabinet door panel again, which can facilitate auxiliary cooling of the lower side of the slit again, avoiding the main nozzle on the lower side spraying cooling water upward to the slit, and the cooling water falls quickly under the action of gravity, resulting in insufficient cooling time for the lower side of the slit and poor cooling effect, thereby ensuring that the lower side of the slit can also be sufficiently contacted and cooled by the cooling water.

Two main nozzles 6 are fixedly installed, and one end of the main nozzles 6 away from each other is fixedly connected with an external water pipe 7. A top seam plate 8 is fixedly installed in the middle of the upper end of the U-shaped frame 5, and a lower baffle 9 is fixedly installed at the lower end of the top seam plate 8. Puncture strips 10 are fixedly installed at both the front and rear ends of the top seam plate 8. An oblique groove 11 is opened on the rear side of the top seam plate 8. The oblique groove 11 is arranged in a V shape, and the rear side of the oblique groove 11 is shorter than the front side. An auxiliary nozzle 12 is arranged on the upper part of the front side of the oblique groove 11, and the upper end of the auxiliary nozzle 12 is fixedly connected with the external water pipe 7; During operation, the MNS switch cabinet door panel to be cut is fixed on the fixed platform 2, and the laser cutting device 4 and the linear motor are started. The linear motor drives the laser cutting device 4 to move from back to front. The laser cutting device 4 is convenient for laser cutting and forming the MNS switch cabinet door panel on the fixed platform 2. At the same time, when the laser cutting device 4 moves from back to front, it will also drive the U-shaped frame 5 to move synchronously. The cooling water is sprayed from the main nozzle 6 through the external water tank and water pump connected by the external water pipe 7. The main nozzles 6 on both sides are convenient for spraying cooling water on the upper and lower sides of the slit of the MNS switch cabinet door panel, so that the slit can be evenly cooled, and the cooling effect is good. At the same time, when the U-shaped frame 5 moves, it will also drive the top seam plate 8 to move synchronously. The puncture strip 10 is conducive to the smooth insertion of the top seam plate 8 into the slit of the MNS switch cabinet door panel and sliding in the slit. The top seam plate 8 is made of a deformable material, so the top seam plate 8 is made of a deformable material. When the seam plate 8 slides in the slit, it will be squeezed by the slit and deformed, so that the two ends of the top seam plate 8 can be tightly abutted and slide in the slit. At this time, the inclined groove 11 will form a space with the two ends of the inner wall of the slit. When the cooling water is transported inside the external water pipe 7, the cooling water will also be synchronously sprayed out from the auxiliary nozzle 12, and the sprayed cooling water will be vertically sprayed to the inner front side of the inclined groove 11. Under the effect of the V-shaped arc of the inclined groove 11, the cooling water is discharged outward from the inner rear end of the inclined groove 11 (the inner rear end of the inclined groove 11 is shorter than the inner front end), which is conducive to cooling the middle part of the inner wall of the slit by the cooling water. Combined with the main nozzle 6 to cool the upper and lower ends of the slit of the MNS switch cabinet door panel, the inner middle part and the upper and lower ends of the slit can be cooled synchronously at the same time, thereby ensuring uniform cooling of different positions of the slit, and the cooling effect is better, avoiding the situation that the MNS switch cabinet door panel is thick and the middle part of the slit cannot be cooled evenly and timely.

[0026] As an embodiment of the present invention, an auxiliary mechanism for auxiliary cooling of the MNS switch cabinet door panel after laser cutting on the fixed platform 2 is also provided, and the auxiliary mechanism includes a gear shaft 13 that is rotatably installed on the lower side of the U-shaped frame 5, and the right end of the gear shaft 13 is meshed with a rack 14, and the lower end of the rack 14 is fixedly installed on the bottom plate 1, and a blade 15 is fixedly installed on the gear shaft 13, and an air guide cover 16 is provided on the upper side of the blade 15, and a support plate 17 is rotatably installed on the lower side of the left end of the air guide cover 16, and the lower end of the support plate 17 is fixedly installed on the U-shaped frame 5, and a spring 18 is fixedly installed on the left end of the air guide cover 16, and the left end of the spring 18 is fixedly installed on the support plate 17, and the upper end of the left end of the air guide cover 16 A magnetic plate 19 is fixedly installed on the side, a magnetic block plate 20 is provided on the left side of the magnetic plate 19, and the lower end of the magnetic block plate 20 is fixedly connected to the bottom plate 1, a collecting box 21 is fixedly installed on the front part of the lower side of the U-shaped frame 5, a liquid throwing plate 22 is obliquely arranged inside the collecting box 21, and side strips are fixedly installed at the upper edge of the liquid throwing plate 22, a rotating shaft 23 is fixedly installed on the rear side of the lower end of the liquid throwing plate 22, and a fixed plate 24 is rotatably installed through the right end of the rotating shaft 23, and the fixed plate 24 is fixedly installed on the rear end of the collecting box 21, and a torsion spring 25 is sleeved on the outer side of the rotating shaft 23, a conical plate 26 is fixedly installed on the rear side of the lower end of the liquid throwing plate 22, and an eccentric plate 27 is fixedly installed on the gear shaft 13 corresponding to the conical plate 26; During operation, when the U-shaped frame 5 moves forward, the gear shaft 13 is also driven to move forward synchronously, and the gear shaft 13 is continuously meshed with the rack 14, which in turn drives the gear shaft 13 to rotate on the U-shaped frame 5. The gear shaft 13 also drives the blades 15 to rotate synchronously, and the wind generated by the blades 15 will blow from the wind guide cover 16 to the slit on the upper side, which is beneficial to auxiliary cooling of the slit. When the U-shaped frame 5 moves forward, the support plate 17, the wind guide cover 16 and the magnetic plate 19 are also driven to move synchronously. When the magnetic plate 19 passes through the magnetic block plate 20 in turn, it will be affected by the magnetic attraction of the magnetic block plate 20. The magnetic plate 19 will then approach the direction of the magnetic block plate 20, and the magnetic plate 19 drives the wind guide cover 16 to rotate on the support plate 17, compressing the spring 18. When the magnetic plate 19 moves to the magnetic block gap on the magnetic block plate 20, it will reset under the action of the spring 18, and the wind guide cover 1 is repeatedly realized in this way. The reciprocating swing of the blade 15 is conducive to evenly blowing the cooling wind generated when the blade 15 rotates to the lower side and the inside of the slit of the MNS switch cabinet door panel, which is conducive to improving the cooling effect at the slit. When the gear shaft 13 rotates, the eccentric plate 27 will be driven to rotate synchronously. The eccentric plate 27 continuously squeezes the conical plate 26. The conical plate 26 drives the liquid-throwing plate 22 and the rotating shaft 23 to rotate on the fixed plate 24, compressing the torsion spring 25. The liquid-throwing plate 22 is conducive to throwing the cooling water collected in the collection box 21 to the slit of the MNS switch cabinet door panel again, which can facilitate auxiliary cooling of the lower side of the slit again, avoiding the main nozzle 6 on the lower side spraying cooling water upward to the slit. The cooling water falls quickly under the action of gravity, resulting in insufficient cooling time for the lower side of the slit and poor cooling effect, thereby ensuring that the lower side of the slit can also be sufficiently contacted and cooled by the cooling water.

[0027] Working principle: When the present invention is used, the MNS switch cabinet door plate to be cut is fixed on the fixed platform 2, and the laser cutting device 4 and the linear motor are started. The linear motor drives the laser cutting device 4 to move from the back to the front. The laser cutting device 4 is arranged to facilitate the laser cutting and forming of the MNS switch cabinet door plate on the fixed platform 2. At the same time, when the laser cutting device 4 moves from the back to the front, it will also drive the U-shaped frame 5 to move synchronously. The cooling water is sprayed from the main nozzle 6 through the external water tank and the water pump connected by the external water pipe 7. The main nozzles 6 on both sides are convenient for spraying cooling water on the upper and lower sides of the slit of the MNS switch cabinet door plate, so that the slit can be well evenly cooled, and the cooling effect is good. At the same time, when the U-shaped frame 5 moves, it will also drive the top seam plate 8 to move synchronously. The puncture strip 10 is provided to facilitate the top seam plate 8 to be smoothly inserted into the slit of the MNS switch cabinet door panel and slide in the slit. The top seam plate 8 is made of a deformable material, so when the top seam plate 8 slides in the slit, it will be squeezed by the slit and then deformed, so that the two ends of the top seam plate 8 can be tightly abutted and fit in the slit to slide. At this time, the oblique groove 11 will form a space with the two ends of the inner wall of the slit. When the cooling water is transported inside the external water pipe 7, the cooling water will also be synchronously sprayed out from the auxiliary nozzle 12, and the sprayed cooling water will be vertically sprayed onto the inner front side of the oblique groove 11. Under the effect of the V-shaped arc of the oblique groove 11, the cooling water is discharged outward from the inner rear end of the oblique groove 11 (the inner rear end of the oblique groove 11 is shorter than the inner front end), which is beneficial to the cooling water against the inner wall of the slit. The middle part is cooled, and the upper and lower ends of the slit of the MNS switch cabinet door panel are cooled by the main nozzle 6. The inner middle part and the upper and lower ends of the slit can be cooled synchronously at the same time, thereby ensuring uniform cooling of different positions of the slit. The cooling effect is better, and the situation that the MNS switch cabinet door panel is thick and the middle part of the slit cannot be cooled evenly and timely is avoided. When the U-shaped frame 5 moves forward, it will also drive the gear shaft 13 to move forward synchronously. The gear shaft 13 and the rack 14 are continuously meshed, which will drive the gear shaft 13 to rotate on the U-shaped frame 5. The gear shaft 13 will also drive the blades 15 to rotate synchronously. The wind generated by the blades 15 will blow from the wind guide cover 16 to the slit on the upper side, which is beneficial to auxiliary cooling of the slit. When the U-shaped frame 5 moves forward, it will also synchronously drive the gear shaft 13 to move forward synchronously. The movable support plate 17, the air guide cover 16 and the magnetic plate 19 move synchronously. When the magnetic plate 19 passes through the magnetic block plate 20 in turn, it will be affected by the magnetic attraction of the magnetic block plate 20. The magnetic plate 19 will then approach the magnetic block plate 20. The magnetic plate 19 drives the air guide cover 16 to rotate on the support plate 17 and compress the spring 18. When the magnetic plate 19 moves to the magnetic block gap on the magnetic block plate 20, it will reset under the action of the spring 18. In this way, the reciprocating swing of the air guide cover 16 is repeatedly realized, which is conducive to evenly blowing the cooling air generated when the blade 15 rotates to the lower side and the inside of the slit of the MNS switch cabinet door panel, which is conducive to improving the cooling effect at the slit. When the gear shaft 13 rotates, it will drive the eccentric plate 27 to rotate synchronously, and the eccentric plate 27 continuously squeezes the conical plate 26.The conical plate 26 drives the liquid throwing plate 22 and the rotating shaft 23 to rotate on the fixed plate 24, compressing the torsion spring 25. The liquid throwing plate 22 is conducive to throwing the cooling water collected in the collection box 21 to the slit of the MNS switch cabinet door plate again, which can facilitate auxiliary cooling of the lower side of the slit again, avoiding the main nozzle 6 on the lower side spraying cooling water upward to the slit. The cooling water falls quickly under the action of gravity, resulting in insufficient cooling time for the lower side of the slit and poor cooling effect, thereby ensuring that the lower side of the slit can also be sufficiently contacted and cooled by the cooling water.
